IMPROVEMENT IN GAS-COCKS FOR SOLDERING.

Specification forming part of Letters Patent No. 123,956, dated February'20, 1872.

Specification describing certain Improvements in GasOocks for Solderingpurposes, invented by WILLIAM L. W ALKER and IDWAL M J ONES, both of thecity and county of Providence and State of Rhode lsland.

This invention consists mainly in combining with an ordinary gas-burnera tube, for the use of jewelers in soldering with the blow-pipe, and acock, arranged in such a wayas to obviate the necessity of removing theburner and screwin g on a tube or socket whenever the blow-pipe is to beused.

Figures 1 and 2 are vertical cross-sections taken through in thedirection of the line 00 m, Fig. 3, Fig. 1 showing a section of a largeburner, in which a blow-pipe is used, and Fig. 2 asection of the tubeused to hold a rubber tube and gas blow-pipe. Fig. 3 is a side elevationof the cock and burner.

A is a gas-burner, made in any of the usual forms. B in Fig. l is atube, with an open top and a division formed of wiregauze, 8, near thetop, intended to furnish a large flame for soldering with a blow pipe. Bin Fig. 2 is turned oii to one side and reduced in size to receive arubber tube with a blowpipe in the end, in which gas is used to solderwith, it being necessary to turn the tube with the rubber away from theupper part of the burner A, as it would otherwise get heated so hot asto destroy the rubber tube. D is a gas-cock, placed at the junction ofthe tubes A and B. It has a single way, the ports of which are widened alittle, so that the gas maybe let onto the tubes A andB at the sametime, or either one shut off.

The operation is as follows: The gas being let onto the pipe 0, and thecock D set to allow it to flow through burner A, it is lighted; and whenthe work is ready the gas is turned onto the tube B, taking fire fromthe flame of the burner A, from which the gas may be shut off entirelyif its light is not needed to see the work by; but when it is necessaryto use the gas blow-pipe, but little gas is turned onto the tube 13,Fig. 2, and the burner A is left burning to see by, as the gas blow-pipegives very little light.

\Vith the usual burn er, the way is, when the work is ready, to shut offthe gas, take the pinch ers and unscrew the burner and screw on an opentube or a socket to receive the tube of the gas blow-pipe, and thenrelight the gas, running the risk of burning the fingers with thehotburner when the pinchers are nothandy; and the wearing out of thescrew-thread and leakage of gas from the continual screwin andunscrewing required, together with the great loss of time consequentupon making the changes, makes our improvement of great utility, as allthese difficulties are obviated by the use of it.

Having thus described our improvement, what we claim as our invention isThe combination of the burner A with the soldering-tube B and cook D,all constructed and arranged substantially as and for the purposespecified.
